This breaks the build because of -Werror in # arch/powerpc, along with thousands of warnings: # # In file included from arch/powerpc/kernel/pmc.c:12: # In file included from include/linux/bug.h:5: #

Undefine this macro so that the runtime patching introduced by # commit 2d1b2027626d ("powerpc: Fixup lwsync at runtime") continues to # work properly with clang and the build no longer breaks. # #
